, BUCKET oannviiie APPARATUS.

T o all 'whom it mary concern.:

ABe it known that l, CHARLES C. Pos'r, a citizen of the Dominion ofCanada, and resiA dent of lVinthrop Harbor, Lake county, Illinois, haveinvented a certain new and useful Improvement in Bucket CarryingApparatus, of which the following is a specification.

My invention relates to carrying-buckets lin' general, for conveyingmaterials from one place to another, but more particularly to apparatusof this kind for receiving and delivering the materials to a concretemixer,

such for example as those employed in putting downl concrete paving, orfor other purposes.

Generally stated,the object of my invention is to provide an improvedconstruction and arrangement whereby the bucket may I y fciency `anddesii'rability'i` ofl a carryingn 35,

travel back and forth on a runway entendn ing horizontally between theplace where the load is received 'and the. point `where the bucket isdumped, and whereby the bucket may be lowered at the receiving place tofacilitate the loading thereof. y

Another object is-to. provide an improved construction and arrangementwhereby said runway may be adjusted or'swung into 'dit` ferent positionsto 'enablethe bucket to rei ceive its load.' i v It-'is alsoan object'to tails and features of construction and combucketeapparatus of thisparticularcharacter..

d To the foregoing andfdther. iisefulends,

my invention consists in matters hereinafter set' forth and claimed.. I

Fig. '7 is au enlarged side elevation ot the bucket and its supportingmechanism, showng` the gate of the bucket in closed posiion.

Fig. 8 is a view similar to Figui, showing the gate of the bucket inopen position.

'ris thus illustrated, my invention coinprises a body .A upon which theconcrete inixer B is mounted, said body being provided with caterpillarsa; or other suitable traction devices, so that the entire mixingplant,including the engine C, mounted on said body; may be moved from place toplace. The said mixer has a receiving-hop per o through which itreceives the materials tobe mixed. An upright frame D is provided at itsupper endwith a swivel d for the horizontally disposed runway E, whichlatter is/adapted by this arrangement to swing around in a horizonmlplane. Said runway is jointed at e, so that its outer endportion caninove up and down, and this outer end-portion which forms an extensionis supported by an arch-like structure F having the lower ends thereofprovided with These.

wheels f to travel on the ground. wheels are provided with forks G which`are connected with the Aarch l? in such manner that they can be turnedabout vertical axes, 1

and a worm-gearing g is provided for ea h fork-spindle, whereby thesewheels can be vMturnedzto the right or to the left to facilitate thesbiftiii of the runway into the da sired position. lie bod A is alsoprovided with an upright frame H which provides a transverse track .itfor the wheel or 'roller l, which latter is mounted in suitable bearingson the Arunway E, so that said wheel travels vided with braces@connected at their upper ende with the outer end ,of the runway E, sothat the arch issuitahly braced and held in osition. i

'"heburket l is provided at its lower end vwith a gate j which ispivoted at 2, and this back and forth on the track fi when the ruiiywayfis shifted laterally'. The arch F is pro-f ietl buch-et. 4i travelerK is provided with wheels il: which travel on the runway E, in

any suitable manner, and this traveler is provided with two sheaves i'and @,disw

6,0 vthe gate (see Fig. 8).

Q, messes der the sheave 9 and then over the sheave fr,

in the manner illustrated. The runway 1s provided with depending arms Lhaving 10 pivoted stops Z at their lower ends, and the arm 13 is rigidwith the arms L and provided with a roller 14 at its end. The traveler Kis provided with a cam 15 to engage the roller 111 during the automaticclosing 15 of the gate 7' (see Fig. 7,) as will hereinafter more fullyappear. The links 3 have upperend-portions 16 which engage thestationary stops 17, when the bucket approaches the hopper b, so thatthe toggle-joints 6 will be 20` operated to lowerl the ate (see Fig. 8).After the load has been discharged from the bucket into the hopper, andthe cable con.- vnections are operated to reverse the motion of Ythebucket, the roller X, which is mounted on a stationary support adjacentthe hop per, engages the under side of the gate to throw the latterupward into closed position. Then the upper endportions 16 of the links3 engage the stops'l, and the cam 15 engages the roller 141, so that thetogglejoints 6 are. brought past the center and against the stops 18 onthe sides o the bucket, in which positions the toggles areselisustainiugand operative to hold the gate -in raised or S5 closedposition. The-cam 15 releases the roller 14k at about the time theVtoggles G strike the stops 18, so that the arms Lthen swing in thedirection in which the bucket is traveling, allowing.;` the` portions 16of the links 3 to pass out from under the pivoted `stops Z, it being"observed that the latter are held by shoulders 19 on the arms L againstpivotal movement relative to said arms 'in this direction. Thetravelervl( is provided 4o with means 2() to engage the portions 2l. onthe bucket, thereby to steady the bucket and prevent it from upsetting`while it is traveling back and forth along the runway. lWhen the bucketagainl travels toward the hopper b, the portioiiis 16 engage the stopsZ, andwhile the cam 15 is passing; under the roller 14;, and while thearnis L are held sta l tionary at this time, it will be seen thatthestopsl swing freely in this direction, whereby these stops do notexert any pressure against the toggle-joints, allowing the lat` ter topass under and approach the stationary stops'17, so that the latter thentrip the toggle-joints, causing the latter to release The cablearrangement traveler` K along the runwayE, and whereby the bucket israised and lowered by allowing the cable 12 to rise andall between e5the sheaves 7 and 8 (the sheave 9 being sup for operating the ported ina loop of said cable) is as follows: The cable 12 has itsy outer end attached to the outer end of the booni or runway E', and its otherend-portion extends downward over the sheave 22, through the hollowswivel (l, and finally to the winding drum-mechanism M on the body ofthe rnachine. The cable 23 is fastened to the traveler .K and extendsrearward and over the sheave 2li and finally to the winding drum- 7 5mechanism, whereby the travelerl may be pulled toward the hopper. Thecable 25 A'is attached at one end to the traveler, extends forward andaround a sheave 26 atthe outer end ol the runway, and then rearward tothe hollow swiveliol, and then downward over the other sheave 27 andfinally to the winding drum-mechanism M, so that when this cable `iswound up on one of the drums Y the traveler is pulled toward the outerend of the runway. Three sheaves 28 are ar- ,ranged just below thehollow swivel cl, on

the runway, to support the three cables thus provided. When theicable 25is operated, the traveler and the bucket are pulled toward the outer endoi the runway, and by then reversing the drum for the cable 12, so thatthe loop in this cable is lengthened, the bucket will be lowered toreceive the load. Then the cable 12 is; wound on its drum of 95 themechanism M, and thisraises the bucket with the loadtherein. The drumlor the' cable 23` is then operated to wind this cable thereon, and thedrinn for the cable 25 is rotated backward, whereby the traveler andbucket are pulled toward thehopper. With this arrangement, it will beseen, the bucket can. be loweredv at any place or at anypoint along' thelength of the runway.

it will be seen that the bucket is dumped 15 automatically by simplybumping it against the stop 17, and that while in dumping position itisheld by the portions 20 and 21, previously explained, against tiltingmove- `rnent on the traveler. No'special operation 110 is necessary fordumping;- the bucket when it arrives in dumping` position, and thebucket thus 'adapted to automatically dump its load, is held by theportions 2O and 21 against tilting' or rocking while traveling 115 alongin elevated position. The entire machine is portable, and can travelalong thev street, so that materials can be picked up anywhere, orwherever convenient, and carried by the bucket to the rotary concretemixer. A
